BAG-HOLDING APPARATUS.

Original application filed December 11, 1922, Serial No 606,176. Divided and this application filed July 30, 1923.

To all who-m it may concern:

Be it known that I, JULIUS GY'rRoN, acitizen of the United States, and resident of Tulsa, county of Tulsa, State of Oklahoma, have invented a certain new and useful Improvement in Bag-Holding Apparatus, of which the following is a complete specification.

The present invention relates to bag-hold ing apparatus, with particular reference to a bin type of construction adapted to hold a bag in inverted position in order to discharge the contents of the bag into other receptacles for either measuring or sacking purposes.

A principal object of the invention is to provide an apparatus of this type particularly adapted for the sacking of material, in which operation a bag containing a con siderable quantity of the material to be sacked may be conveniently supported in position for discharging the material into a measuring device for measuring a smaller quantity of the material and dumping the same into a passage communicating with the sack to be filled. The improved construction of apparatus herein described is designed to permit operation in a quick and easy manner for mounting a bag in dumping position and for removal of the empty bags and replacing with full ones.

lVith this general object in view, the invention will now be described by reference to the accompanying drawing illustrating one form of construction which I have devised for embodying the proposed improvements, after which those features deemed to be novel will be particularly set forth in claims.

In the drawing Figure l is a perspective view illustrating an apparatus constructed in accordance with the present invention;

Figure 2 is an enlarged vertical sectional view of the same; and

Figure 3 is similar view taken atright angles to Figure 2, with dotted lines representing the bin in open position.

Referring now to the drawing in detail, this illustrates the improved construction as comprising a box-like frame 6 supported by legs 7. The rear wall of this frame is Serial No. 654,771.

open part way from the top for accommodating the swinging movements of a pivoted bin 8, the lower rear edge of which is hinged as indicated at 9, to the top edge of said rear wall of the frame 6 (see Figure 3). Preferably the top of the bin is of the same width as the frame 6, while the lower portions of the side walls of the bin are offset inwardly along the lines 10 sufficiently to fit inside the frame 6, thereby reinforcing the support of the bin when in vertical position. The front wall 11 of the bin is pivoted to the lower front corners of the bin, as indicated at 12, and the bin is provided with a flanged top or cover 13 hinged at 14 to the upper margin of the rear wall of the bin the flanges 13 of said cover being adapted for retaining engagement with the front wall 11 when the parts are in upright position, as illustrated in Figure 1. The interior faces of all the walls of the bin, and its cover 13, are provided with barbs 15 for suitable engagement with a bag (not shown) designed to be placed within the bin in inverted position, the barbs of the wall 11 being somewhat straighter than the others, as illustrated in Figure 3. The bin structure is such as to allow it to swing from the full line to dotted line position represented in Figure 3, the sections of the bin thereby opening up for removing an empty bag and inserting a filled one, the return of the bin to vertical position being facilitated by the action of counterweights 16 carried by cords 17 attached to the upper rear corners of the bin. The counterweight cords operate over pulleys 18 at the upper ends of housings 19 attached to the sides of the frame 6 and serving as runways for the weights 16. Staples 20 are inserted through openings 21 in the upper ends of the housings 19 to adjustably limit the upward movements of the weights 16, and thereby regulate the outward and downward movement of the bin.

lVithin the frame (3 and above a horizontal partition 22 therein is arranged a fixed hopper bottom 22 in position to receive material as discharged from the bin, and in turn to discharge such material through. an opening 21 in said partition into the measuring device. The size of the outlet passage 25 from this hopper is regulated by means of a pair of slides 26 adjusted from opposite directions by manipulation of handle portions 27 at opposite sides of the frame 6. The discharge of the material from the hopper is effected by the operation of a lever 28 fulcrumed in a bracket 29 at the front of the frame 6, as illustrated in Figure 1, the material thus discharged being received in a measuring device which is not illustrated or described herein in detail, as the same forms a part of my copending application Serial Number 606,176, filed December 11, 1922, of which the present application is a division.

In the use of the abovedescribed apparatus, the bin 8 is pulled backward against the action of the counterweights 16-intothe position indicated by the dotted line in Figure 3, in-which operation the front wall 11 swings forward and the cover 13 downward, as shown, this opening movement of the bin being limited by the staples 20. With the bin in. open position, a bag containing the material may be placed upon the l rear wall of the bin, with the mouth of the bag open at the hinge end of the bin, after which the cover 13 is swung up against the bottom of thebag and the bin then lifted into upright position to allow the contents of the bag to discharge into the hopper 23; the flanged structure of the cover 13 serves to securely retainthe parts in this upright position. This brings one side of the bag in engagement with the front wall 11 of the bin, thus automatically engaging its barbs with the front face of the bag, and thecombined action of all the barbs 15 serves both to support the bag and hold it open, i. e., keeps it from collapsing as the material flows out of it. The slides 26 are adjusted to regulate the size of the discharge opening 25 of the hopper 23, which will vary accord ing to the flowing consistency of the material, some flowing more freely than others accordingto the fineness or granular character of the material; for example, rice will flow somewhat more freely than beans, coffee and the like, and on the other hand some material will have a tendency at times to cake, such as sugar and the like, and the outlet from the hopper must be regulated to suit the requirements by means of the slides 26.

As soon as the supply bag is empty, the bin is again opened, which action strips the bag off from the barbs of the front wall 11, and the attendant then proceeds to remove the bag from the remaining barbs and replace with another full bag ready to repeat. the operation, which replacing operation is of course greatly facilitated by the fact that both the top and one side of the bin are entirely open, as illustrated in Figure 3.

From the foregoing it will be apparent that I have devised a practical and efficient device for carrying out the desired object of the invention, and While I have illustrated and described what I now regard as engagement with the bag to support the latter in discharging position.
